i feel like all of those saucers are just experimental military aircraft

yes, we’ve literally found alien life in the form of bacteria

this will be the realalexspat if aliens invade

no

I’m no expert, but I feel like it would be more surprising if there were none. I think there’s probably something out there, even if it’s just some single-celled organisms billions of light years away.

It would be a statistical anomaly if they didn’t exist.
Now too be sure, the vast, VAST majority of them are going to be something like single celled organisms (or even simpler), an incredibly minority might be comparable with simple multicellular organisms, and even fewer will be significantly complex, but they still probably exist. If earth can have life, so can other hospitable planets.
Same rules throughout the universe, and I don’t believe in anything supernatural that makes earth special 🤷‍♂️
